SHIPPING CONFIGURATION

individual bombs are listed in fig 1-20. The basic difference between the bombs listed in fig 1-20 is their size and weight. The following description of the Mk 80 (series) bomb is applicable to all bombs within the Mk 80 (series) unless otherwise noted. SHIPPING CONFIGURATION The bomb body (fig. 1-21) is shipped with a plastic plug installed in the nose and tail fuze well to prevent damage to the internal threads and to keep out moisture. The aft end of the bomb body has a metal shipping cap installed. Plastic lug caps are installed in the suspension lug wells, and a plastic plug is installed in the fuze charging receptacle well. Some bombs contain a hoisting lug packaged in the tail fuze well. Bombs are shipped on metal pallets. The number of bombs loaded on each pallet depends on the bomb size. For example, six Mk 82 bombs can be shipped on a pallet, three Mk 83 bombs can be shipped on a pallet, and two Mk 84 bombs can be shipped on a pallet. Refer to Airborne Weapons A1. A2. A3. A4. A5. A6. A7. Packaging/Handling/Stowage, NAVAIR 11-120A-1.1 or appropriate MIL-STD for more information on shipping configurations. FUZE WELLS The bomb body is designed with a nose and tail fuze well. These wells are internally threaded to receive either mechanical or electric fuzes. FUZE CHARGING CIRCUIT The forward and aft charging tubes are installed at the factory and contain the electric fuze wire harness. When electric fuzing is used, the wire harness provides a path for the charging current from the fuze charging receptacle to the forward and aft fuze wells. SUSPENSION LUGS There are two suspension lug wells for the installation of suspension lugs. The suspension lugs are spaced 14 or 30 inches apart, depending upon the size REVIEW NUMBER 5 ANSWERS TO QUESTIONS Q1. THROUGH Q7. All electric capability for Mk 80 with either conical or retarding fins, thermally protected bombs, and laser-guided bombs is provided by Mk 344 and Mk 376 electric bomb fuzes. No unusual RADHAZ precautions taken when using Mk 344 or Mk 376 fuzes because they are classified as HERO SAFE. The Mk 376 electric fuze is used for retarded delivery of the Mk 80 (series) bomb. The functions of the Mk 31 safety device are to adapt the fuze to the fuze well of the bomb. mechanically safe the fuze and to unlock the timer-decelerometer. The Mk 122 Mod 0 arming safety switch is used to open a circuit and provide a RADHAZ shield to prevent electromagnetic radiation from entering the fuze circuits. The Mk 43 Mod 0 target detecting device is used to provide airburst capability for electrically fuzed Mk 80 bombs. A thermal battery, initiated by a +300 volts dc or striker rod, is used to power the internal circuitry of the TDD. 1-24
